The Office of the Public Guardian (OPG) provides decision-making mechanisms for individuals who are unable to make personal, non-financial decisions for themselves. The OPG does this through the Personal Directives Act, the Adult Guardianship and Trusteeship Act and the Mental Health Act. The OPG also administers the Personal Directives Registry and the Adult Guardianship and Trusteeship Registry.

Offices are located throughout the province of Alberta.
